トピック：Rules of Engagement at Sea（海上交戦の国際法）
Incidents at sea over maritime resources in the South China Sea have continued for more than a decade. Because of a weak collaboration among the maritime law enforcement agencies and the disputes over islands and maritime title, there remains a risk of conflicts. In light of the importance of the region, this presentation discusses the basic structure of the law of the sea and public international law governing the use of force at sea. It will review recent updates of coast guard laws in China, Indonesia, Malaysia, the Philippines, Thailand and Vietnam, with particular attention to the significance of the “maritime zone” concepts that appear in several laws and potentially excessive authorization of use of weapons.
